'''AlphaServer''' is a series of [[server computer]]s, produced from 1994 onwards by [[Digital Equipment Corporation]], and later by [[Compaq]] and [[Hewlett-Packard|HP]]. AlphaServers were based on the [[DEC Alpha]] [[64-bit]] [[microprocessor]]. Supported [[operating system]]s for AlphaServers are [[Tru64 UNIX]] (formerly Digital UNIX), [[OpenVMS]], [[MEDITECH]] MAGIC<ref>[https://ftp.zx.net.nz/pub/archive/ftp.hp.com/pub/alphaserver/archive/DECinfo/info_3/infosheet/MEDITECH_MAGIC_on_the_Compaq_06may1999LIW0LIPF.pdf MEDITECH MAGIC on the Compaq Alpha platform]</ref> and [[Windows NT]] (on earlier systems, with AlphaBIOS [[ARC (specification)|ARC]] firmware), while enthusiasts have provided alternative operating systems such as [[Linux]], [[NetBSD]], [[OpenBSD]] and [[FreeBSD]].

The Alpha processor was also used in a line of [[workstation]]s, [[AlphaStation]].

Some AlphaServer models were rebadged in white enclosures as '''Digital Servers''' for the Windows NT server market. These so-called "white box" models comprised the following:

* '''Digital Server 3300/3305''': rebadged AlphaServer 800
* '''Digital Server 5300/5305''': rebadged AlphaServer 1200
* '''Digital Server 7300/7305/7310''': rebadged AlphaServer 4100

As part of the roadmap to phase out Alpha-, [[MIPS architecture|MIPS]]- and [[PA-RISC]]-based systems in favor of Itanium-based systems at HP, the most recent AlphaServer systems reached their end of general availability on 27 April 2007. The availability of upgrades and options was discontinued on 25 April 2008, approximately one year after the systems were discontinued. Support for the most recent AlphaServer systems, the DS15A, DS25, ES45, ES47, ES80 and GS1280 is being provided by HP Services as of 2008. These systems are no longer supported by HP.

== Models ==
In approximate chronological order, the following AlphaServer models were produced:

The AlphaServer SC was a [[supercomputer]] constructed from a set of individual DS20L, ES40 or ES45 servers (called "nodes") mounted in racks. Every node was connected to every other node using a [[Quadrics (company)|Quadrics]] elan3 interconnect and the systems were designed and used primarily for [[high-performance technical computing]]. An AlphaServer SC45 supercomputer was still ranked #6 in the world as late as November 2004.<ref>{{cite web|url=http://www.top500.org/lists/2004/11 |title=November 2004 &#124; TOP500 Supercomputer Sites |publisher=Top500.org |access-date=2019-10-10}}</ref>
